摘　　要：本文用模糊数学理论建立了崩塌易发性预测模型,模型中通过对崩塌影响因素的分析,选取8种因素作为预测因子,4个等级作为评价集,并引入k次抛物型模糊分布作为隶属函数。之后采用层次分析法求出权重,使用matlab软件检验权重的一致性并计算结果向量,从而实现对崩塌发育影响因素严重性等级综合评判。实例表明:模糊综合评价方法可操作性强、效果较好,可在一般崩塌发育影响因素分析评价中广泛应用。This paper uses the fuzzy mathematical theory to establish a collapse-prone prediction model. This model selects eight kinds of factors as predictors, four levels as evaluation set and the k-th parabolic fuzzy distribution as the membership function, based on the analysis of the collapse of the influencing factors. Moreover, using the analytic hierarchy process for obtaining the weight and matlab software to test weights consistency and calculate the fuzzy synthesize result vector, so as to realize the comprehensive evaluation of the collapse developmental impact factors severity level. The applied example shows that fuzzy comprehensive evaluation method operates well and can be widely used in the evaluation of the general collapse developmental impact factors.
